“Caffeine is the new black”

“Caffeine is the new black” is a saying that has been printed on many images—especially coffee mugs. Black coffee contains caffeine.
 
“HEY YOU!! sleep is over-rated!! Caffeine is the new black!” was posted on Twitter on August 18, 2009. However, the saying didn’t become popular until 2011.
